Prac 7 Factors postulateing the prize of answer Intro The factors that affect the respect of a chemical substance reply ar important to understand due to the wideness of many such replys to our health, well-being The rate of a reaction is governed by the contact theory. In order for a reaction to occur, there mustiness be a encounter in the midst of reactant molecules. This collision must suffer enough energy to circumvent and path the appropriate bonds as well as have the slide down orientation when colliding. When all of these things happen, a chemical reaction has occurred. If we atomic descend 50 subjoin the amount of these favourable collisions, then we increase the rate of the reaction.(1) and comfort. Purpose/Objective: The aim of this lab is to lionise the effect of temperature and concentration on the rate of a chemical reaction. surgery: divert refer to Heinemann Chemistry 2 student workbook pg. 138-140 Calculations: Please refer to prac she et for full calculation Evaluation: unmatched of the factors that affects reaction rate is reactant concentration. The to a greater extent(prenominal) reactant molecules in a given(p) argona, the greater the number of collisions possible, when the concentration increases from 0.05 M to 0.125 M to 0.2 M, the rate of reaction ordain increase, the less time taken for the X mark to disappear.

other factor that affects the rate of reaction is temperature. As temperature increases from 17C to 40C to 60C time for beat to disappear decreases, hence the reaction speeds up but this conclusion is to be expected because increasing temperature of resoluten! ess means reactants are moving faster .they collide more frequently and with more energy. They have more chance of overcoming energizing energy and reacting. service and Limitation: There were some problems when we were doing this investigate and these errors have produced a minor uncertainty in our prove. * It was grueling to observe when the O mark completely cannot be seen. A light detector could be used in this experiment to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
